The Corvidae family--jays, crows, ravens, magpies--are fast becoming one of my favorite bird families. Each time I get acquainted with a new species, I am enamored.

I encountered my first Gray Jay in Alaska, in 2012, on the campus of the Denali National Park Visitor's Center. Several were scavanging for crumbs around the side walk near where I waited for transportation--a day-making sighting on my last day in the park.

Gray Jays are a wide-spread resident of North America's boreal and sub-alpine coniforest forests, where they have developed adapative characteristics that enable them to surive the hostile winters.

Gray Jays feed primarily on arthropods, berries, carrion, nestling birds and fungi, such as mushrooms, but they quickly learn to recognize and seek out novel foods, like cheese, raisins, and bread. They cache food by coating the food with copious amounts of saliva produced by their large salivary glands.

After the food is coated, they tuck it under flakes of bark, lichen, or in the fork of a branch, and sometimes add another piece of bark or lichen on top to cover it. In addition to their hoarding habits, these jays have thick, fluffy plumage that can cover their legs and feet while perched and their nares are covered with tiny feathers. The jays in the images above were observed in Riding Mountain National Park, Manitoba, in October, flying from perch to perch as they hunted for insects.

Above, you see me in Churchill, Manitoba, also in October, enjoying the surprise boldness of this species. A succession of jays flew from the trees to take kibbles from my hand on this windy, snowy morning as I stood on the porch at Blue Sky Dog Kennels.

Our bird-banding morning on November 16, 2014 at Seven Islands State Birding Park was chilly but rewarding!

Sometimes its a little hard to get out of bed way before dawn, especially when you're anticipating at least four hours of being out in the cold, but seeing the wintering bird population at Seven Islands State Birding Park makes it well worth the effort.

During the winter months we have the great pleasure of hosting wintering sparrows in the grassland and shrubby habitat of the park.

Sparrows like to hang out on the stems of dead flowers and grasses eating seeds or foraging on the ground underneath. Often referred to as "little-brown-jobs", they are not really brown and dull as suggested, but display a bright array of neutral colors--brown, tan, rust, gray, cream, black and white--arranged in intricate contrasting patterns. The nickname, of course, also refers to the fact that that they aren't the easiest of birds to see. You may only catch a flash of brown as a shy sparrow disappears into the nearest thicket!

The Swamp Sparrow above was still growing in new feathers, shown as white around his face, but when the fresh plumage grows in fully, he will look more like the sparrow below with a mostly gray face, dark crown and rust-colored wings. Swamp Sparrows breed in the boreal forests of Canada and the northeastern United States and prefer brushy habitat that is either wet or near water.

I was introduced to Swamp Sparrows at Seven Islands in 2009, along with the Savannah Sparrow, Grasshopper Sparrow, Fox Sparrow, White-crowned Sparrow and Field Sparrow--all at the banding table.

Above, Billie Cantwell, banding apprentice, and Mark Armstrong, Master Bander, discuss plumage characteristics that help to determine the age of this Swamp Sparrow.

While walking up and down hills and removing birds from nets, banding team members stay warm. While waiting for the next net-run, it gets chilly and it's time to bundle up. In the image above, Patty Ford is showing Eddy Whitson the photo she took of the Swamp Sparrow.

Above, a Field Sparrow with its new band just before release. Field Sparrows both breed and winter in Tennessee. The banding program at Seven Islands is giving biologists valuable information about the area's birds, the impact of changing land management practices on the bird population, and information about the health and site fidelity of the bird species.

Above and below, banding team members remove birds captured in a net.

Some net-runs, such as this one, may hold a large number of birds. The birds are held in soft cloth bags until they are processed and released.

Below, Janie Kading helps Dawn Johnson separate the bags and safely hang them on the carousel.

When the weather is cold as it was this day, in the mid 30's F, the banders band the bird, determine its age and release it without taking the time to measure the wings and tail or weigh the bird. This allows the bird to get back to its activities more quickly. Measurements help document the bird's health and general characteristics for referrence when recaptured.

The White-crowned Sparrow breeds in northern Canada and the western United States and starts to arrive to winter in Tennessee around October. These sparrows are most often found on the ground kicking up leaf litter with double-footed scratching.

For the Love of It...

...the sage sees heaven reflected in Nature as in a mirror, and he pursues this Art, not for the sake of gold or silver, but for the love of the knowledge which it reveals.Sendivogius (1750)

Your Uncapped Creativity...

"There is a vitality, a life force, an energy, a quickening that is translated through you into action; and because there is only one of you in all time, this expression is unique. If you block it, it will never exist through any other medium and it will be lost. The world will not have it. You must keep that channel open. It is not for you to determine how good it is, nor how valuable. Nor how it compares with other expressions. It is for you to keep it yours, clearly and directly." ----the great dancer, Martha Graham

Whooping Cranes

Whooping cranes were on the brink of extinction in the early 1940's with only 15 remaining in the population that migrates from their nesting grounds in Canada to the coast of Texas. Today, after many years of help, this population has reached a record number of 266. In order to safeguard this species, biologists are using an innovative method to imprint captive reared Whooping cranes and teach them to migrate behind ultralight aircraft. In this way, Whooping cranes have been restored to the Eastern flyway and a separate wild migrating population has been established. As more and more people have the privilege of seeing these birds, Whooping cranes have become ambassadors for our wetlands and for all species in need of our assistance. Support our wildlife.
